Grand Designs House of the Year

In this first episode, Kevin McCloud visits five homes built for country living. Enormously varied in size and style, they are: a house disguised as a giant shard of flint; a beautifully crafted timber farmhouse in Somerset; a low budget home made of shipping containers in Northern Ireland; an elegant eco house in Cambridgeshire, designed for a passionate birdwatcher; and a stunning modern glass villa with a spectacular jagged roof designed to look like mountain peaks. Find out which of the five make it through to the final shortlist - and discover what it takes to be crowned Riba: House of the Year 2015.
